High percentages of P. tomentosus spores germinated on media supplemented with bark extracts from roots of white and black spruce. Best germination was on extracts from the inner bark of black spruce. Spore germination was significantly higher on extracts from root bark of diseased trees than on those from healthy trees.

Sieve Cell

Cell dimensions and volume changes were studied in black spruce phloem by microscopic techniques.It was found that sieve cells measure 4 mm in length and 30 μm in diameter and constitute on the average 52.2% of the volume of the inner bark. However, sieve cell volume decreases gradually from 62.8% at the cambium to 38.7% in the outer dead phloem as a result of the collapse of these elements. In contrast, the volume of longitudinal parenchyma increases from 28.7% at the cambium to 43.7% in the outer dead bark.Sclereids possessing thick and multilayered walls make up on the average 3.4% of the inner bark. Sclereid volume increases from 2.8% at the cambium to 9.6% in the outer bark. On the average, rays constitute 6.4% of the inner bark, increasing from 5.7% at the cambium to 8% in the outer bark as a result of dilation.
